Quick Start

Prerequisites

  • A7 device (iPhone 5s, 6, 6 Plus, iPad Air, iPad Mini 2/3)
  • Computer running Windows, Linux, or macOS
  • USB cable

└─────────────┘     └──────────────┘     └─────────────┘

Automated Method - Linux/macOS (Recommended)

  1. Jailbreak with Checkra1n 0.10.2
  2. Run setup and transfer scripts: 
    # Terminal 1: Start proxy
./setup_proxy.sh

# Terminal 2: Transfer files and bypass
./transfer_files.sh
ssh root@127.0.0.1 -p 2222  # Password: alpine
cd /var/root && ./bypass_device.sh

# Terminal 3: Transfer patch
./transfer_patch.sh

# Back in Terminal 2 SSH session
./finalize_bypass.sh
  3. Complete by tapping "Connect to iTunes"

Automated Method - Windows

  1. Jailbreak with Checkra1n 0.10.2
  2. Run setup_proxy.ps1 in PowerShell
  3. Use WinSCP to transfer files and follow on-screen instructions
  4. Complete by tapping "Connect to iTunes"

Detailed Instructions

Step 1: Jailbreak the Device

Download Checkra1n:

Jailbreak Process:

  1. Connect device to computer
  2. Run Checkra1n and follow on-screen instructions
  3. Device will enter DFU mode

Important Troubleshooting:

⚠️ Known Issue: Freezing at "Right Before Trigger (this is the real bug setup)"

Solution:

  • Wait ~15-20 seconds at the "Right Before Trigger..." screen
  • Unplug the device
  • Wait 1-2 seconds
  • Plug device back in
  • You should immediately see "Booting Up"
  • If not, restart the jailbreak process
  • If repeated failures occur, restore iOS firmware in iTunes and retry

Step 2: Setup Host Environment

Choose your operating system:

Linux / macOS Setup

Install libimobiledevice:

Ubuntu/Debian:

sudo apt update
sudo apt install libusbmuxd-tools libimobiledevice-utils

Fedora/RHEL:

sudo dnf install libusbmuxd-utils libimobiledevice-utils

Arch Linux:

sudo pacman -S libusbmuxd libimobiledevice

macOS (with Homebrew):

brew install libusbmuxd libimobiledevice

Optional (for automated file transfer):

# Ubuntu/Debian
sudo apt install sshpass

# Fedora/RHEL
sudo dnf install sshpass

# macOS
brew install hudochenkov/sshpass/sshpass

Start Proxy:

./setup_proxy.sh

Keep this terminal open!

Windows Setup

Download Required Tools:

  1. libimobiledevice - Download v1.3.17
  2. WinSCP - For file transfer to device

Setup:

  1. Extract libimobiledevice.1.2.1-r1122-win-x64.zip
  2. Open PowerShell in the extracted directory

Option A: Automated (Recommended)

.\setup_proxy.ps1

Option B: Manual

.\iproxy.exe 22 44
  • Port 22 = Local masquerade port
  • Port 44 = SSH port on device (Checkra1n default)

Keep this PowerShell window open!

Step 3: Bypass Activation

On Device: Navigate to "Choose a Wi-Fi Network" screen

⚠️ DO NOT connect to WiFi yet

Method A: Linux/macOS Automated (Recommended)

Terminal 1 (already running from Step 2):

./setup_proxy.sh  # Keep this running

Terminal 2 - Transfer files and start bypass:

# Transfer bypass scripts to device
./transfer_files.sh

# SSH into device
ssh root@127.0.0.1 -p 2222
# Password: alpine

# On device, run bypass script
cd /var/root
./bypass_device.sh
# Leave this SSH session open

Terminal 3 - Transfer patched file:

./transfer_patch.sh

Back in Terminal 2 (SSH session):

# Finalize the bypass
./finalize_bypass.sh

On Device: Tap "Connect to iTunes" at bottom of WiFi screen ✓

Method B: Windows Automated

Connect to Device:

Open a second PowerShell window and connect via SSH:

ssh root@127.0.0.1

Password: alpine

Setup WinSCP:

  • Protocol: SCP
  • Host: 127.0.0.1
  • User: root
  • Password: alpine

  1. Transfer scripts to device via WinSCP:

    • bypass_device.sh → /var/root/
    • finalize_bypass.sh → /var/root/

  2. In SSH session, run:

    cd /var/root
chmod +x bypass_device.sh finalize_bypass.sh
./bypass_device.sh

  3. Transfer patched file via WinSCP:

    • Transfer mobileactivationd to /usr/libexec/mobileactivationd

  4. Finalize bypass:

    ./finalize_bypass.sh

  5. On device: Tap "Connect to iTunes" at bottom of WiFi screen

**Method C: Manual Commands (Any OS)

Phase 1 - Prepare Device:

mount -o rw,union,update /
launchctl unload /System/Library/LaunchDaemons/com.apple.mobileactivationd.plist
rm /usr/libexec/mobileactivationd
uicache --all

Phase 2 - Transfer File:

  • Using WinSCP, transfer mobileactivationd to /usr/libexec/mobileactivationd

Phase 3 - Finalize:

chmod 755 /usr/libexec/mobileactivationd
launchctl load /System/Library/LaunchDaemons/com.apple.mobileactivationd.plist

Complete:

  • On device, tap "Connect to iTunes" at bottom of "Choose a Wi-Fi Network" screen

Automation Scripts

This repository includes automation scripts to streamline the bypass process:

Script Platform Purpose
setup_proxy.sh Linux/macOS Automatically starts iProxy with correct ports
setup_proxy.ps1 Windows Automatically starts iProxy with correct ports
transfer_files.sh Linux/macOS Transfers bypass scripts to device
transfer_patch.sh Linux/macOS Transfers patched mobileactivationd to device
bypass_device.sh Device (SSH) Automates Phase 1 commands
finalize_bypass.sh Device (SSH) Automates Phase 3 commands

Benefits:

  • ✅ Cross-platform support (Windows, Linux, macOS)
  • ✅ Reduces human error
  • ✅ Faster execution
  • ✅ Visual progress indicators
  • ✅ Error checking at each step
  • ✅ Automated file transfer (Linux/macOS)

Troubleshooting

Checkra1n Freezes

Cannot Connect via SSH

  • Ensure iProxy is running
  • Verify device is jailbroken (Checkra1n app should be visible)
  • Try reconnecting USB cable
  • Restart iProxy

Permission Denied Errors

  • Ensure you're logged in as root
  • Check that filesystem is mounted read-write: mount -o rw,union,update /

Device Won't Complete Bypass

  • Verify mobileactivationd was transferred to correct location: /usr/libexec/mobileactivationd
  • Check file permissions: ls -la /usr/libexec/mobileactivationd (should show -rwxr-xr-x)
  • Try restarting device and re-running finalization script
